Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Short io MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on connect.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
What is the Short io MCP server, and what's possible with it?
The Short io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Short io account. It provides structured and secure access to your branded short links, so your agent can create and manage links, retrieve analytics, organize domains, and optimize your link campaigns automatically.
- Automated branded link creation and management: Instantly generate new short links, fetch details, update metadata, and organize your links by domain—all on demand.
- Comprehensive click analytics and statistics: Retrieve detailed click metrics for individual links or aggregated data by domain to track performance and measure engagement.
- Popular path and traffic insights: Analyze the most visited short link paths in your domains over time to understand which content resonates with your audience.
- Granular permissions and access control: Check and manage user permissions on links within your domains, ensuring secure collaboration and streamlined workflows.
- Open Graph and targeting customization: Review and adjust Open Graph properties for better link previews and set up advanced targeting rules by region or country to maximize reach.

FAQ
What are the differences in Tool Router MCP and Short io MCP?
With a standalone Short io MCP server, the agents and LLMs can only access a fixed set of Short io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Short io and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with Codex?
Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Short io tools.
Can I manage the permissions and scopes for Short io while using Tool Router?
Yes, absolutely. You can configure which Short io scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
How safe is my data with Composio Tool Router?
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Short io data and credentials are handled as safely as possible.
